HI; SKS needs a Murrays spring fireing pin and spring, who has them in Canada or are we going direct to the USA Murrays gunsmith?
Also what are the CCI no 34 MIL-Spec primers like to use? Will these help with the slam fire issue? Instead of my current Federal large rifle.

federal primers are known to more sensitive but that said I used federal blue box for years in my M14 type rifles.
The CCI milspec primers should be much harder.

p.s. I wouldn't mind a murray's firing pin and spring as well so if you end up ordering direct...... order 2 , I'll take one hehehe
 
Slam fires are normally the result of a dirty, or grease clogged firing pin channel - even with ever so slightly softer primers. Pull it apart, clean it down, don't put any lubricant in the channel, it should be bone dry, put it back together.

A buddy of mine went to shoot his rifle and did not need my war Ings to clean it after a range trip, and to soak the bolt, disassembled in a bit of mineral spirits, his slam fired, he shat himself, I half chuckled, but he took a Sledge to the barrel, poor rifle never will be fired again

does he want to sell the trigger group?
seriously I need one hehehe
 
It's good that he did that, sounds dangerous in many ways.
I found on Amazon.ca some of the pipe cleaners with wire bristles, they're just right for cleaning firing pin channels as well as the gas port thru the barrel - tiny wire brushes. Good around the shop in general too. I strip my SKS completely every time I shoot, including the firing pin channel, that's the worst place to get rust/cr-p.
 
Agreed, I strip them down, and clean all parts, if it's just a quick non corrosive clean I'll put it in some mineral spirits or some cleaner of the like, and let it soak then strip and scrub

Why does it "need" a murray's FP? Keeping a clean bolt is the simplest way to prevent slam fires in an sks.

And what kind of ammo are you using?

Some modern soviet and Ukranian 7.62x39 commercial ammo has a reputation for popped primers in the sks-- steel cased, berdan primed. These popped primers can lead to slam fires in free floating AND spring loaded pins.
 
and that's the thing with some semi autos and cleaning habits become quite important.
In the M305 rifles (and other m14types) , pierced primers are often not noticed and small chunks of primer brass can and does make it thru the firing pin hole and into the channel. A situation that will cause the firing pin to bind up and lead to slam fires and out of control mag dumps. It's not full auto if it's not controlled so I just call that condition a mag dump hehe
 
HI, Thanks. Only brass reloads with federal primers, Hornady 123 bullets. Primers were not proud (up).
Firing pin taken out and cleaned twice same slam bang. Russian referb BBQ matching number in good shape, shoots small groups.
So got a brick of CCI 34 Mil-spec to-day, 80 bucks, will see if that help. Made sure I deep seated the primers.
Details to follow later.

PS; I do not own a sledge hammer.
 
Per my earlier post, how are you cleaning 'the firing pin' ? How are you addressing the f-p channel ? Is it clean throughout, and does the tip of the f-p have any marking indicating it's sticking there ? And Boris's point about the sear could be the answer. Does anyone know what primers are in the US commercial x39s, like the Hornady SSTs ? Never heard about any of them 'self-firing'.
 
Slam fires when the bolt is pulled back and released to charge forward to load a round into the chamber.
These are all home made reloads.
Firing pin is dry and no oils are present.
Firearm was bought from a store as imported from wholesaler.

This sounds like a trigger issue.

Slowly close the bolt on remaining rounds and fire them one by one. Next batch of reloads use Magnum Rifle primers, these have thicker cup this will prevent slam fires.
Leave regular primers for bolt actions

^^^this is a VERY BAD idea, and a quick way to break or even lose a thumb or seriously injure your hand. Never close the bolt by hand on an sks. Especially one with with a potentially faulty hammer.

Any rifle that fires without the trigger being pulled, should not be fired especially an sks.

If anything, find another trigger group and install it to see if the problem persists. Test the trigger first with NO round chambered to see if the hammer falls when you charge the bolt home.

If it does not, load only one round at a time to see if the hammer falls and fires the chambered round when the bolt falls into battery.

If it does not. The problem is your trigger group-- likely the sear-to-hammer engagement.

Probably nothing wrong with the gun at all . as the gentleman said home made loads . it's more then likely the primers are too soft . brother try some good old military ammo and if it doesn't happen with it than it's the primers . have you ever ejected a round from a chamber and looked at it to only see a small indent from the firing pin ? well hence the term slam fire and as one jolly member said Mag dump . it's the primers . I'll bet you a beer . your only a half hour drive from my place . $80 dollars for 1000 primers . ouch . it's a sign of the times .

good luck with those primers . I hope they work . as I said try some military stuff . Chinese or Czech . clean after of course . if it screws up with that ammo tell the store they owe you another rifle . don't play with it . good luck and let us know what happens .
